Nice Little Amp
Style: 4 Channel
Plenty of power for the 2004 Grand Cherokee, pushing 4 old school Jensens (2 @ 6x9, 2 @ 5 1/4.) Compact enough to go where the stock Infinity amp was, but way better volume and clarity.

Mighty, small, clean and loud
Style: 4 Channel
Great small profile if you have limited space. All the hookups for running front and back speakers. Plenty of power to make your vehicle rumble with sound. One caveat, if you don't have one, buy a line output converter (LOC), you'll need it to condition down regular powered speaker output to line level (low output) so you get clear audio and not a distorted signal. YouTube has plenty of DIY to glean from on tweeking the LOC properly. Cheers you DIY community! ... show more

Gets really hot

Review Image by robby hise
This is a solid amp for my Harley Road Glide. I have it mounted in the saddle bag because it is too big to fit in the front fairing. It gets really hot after long rides so do not put anything in the same saddle bag as the amp. I made some fabrication to the saddle bag to allow air flow, but it still gets really hot. Other than that, great amp. ... show more
